PSIQUANTUM SHOWS AN 8×8 OPTICAL CIRCUIT SWITCH WITH 1.2 DB LOSS FOR AI DATA CENTER NETWORKS

Summary from the TLDR Hardware newsletter

PsiQuantum unveiled an 8×8 optical circuit switch built on the silicon photonics platform it developed for quantum computing, measuring typical insertion loss of 1.2 dB, 40 dB crosstalk, and under 3 ms reconfiguration without amplification. Samples are going to select customers, with commercial products promised in the coming months. A 64×64 barium titanate switch used in its quantum systems isn't needed for this first version but offers a path to faster future parts.
